In the phase diagram of a binary system one often encounters a compositional region in which two phases coexist. A common practice is to use the Lever Rule to describe the distributions of the two coexisting phases. However, if the binary system is a complete solid solution system, the Lever Rule cannot be used. A new type of distribution has been derived for a solid solution system without solubility gap. Application of the theory to pure and modified lead-zirconate-lead-titanate (PZT) systems shows excellent agreement with the experimental data. Several disputed facts about PZT are also explained satisfactorily.
